IMPROVEMENT IIN CRANBERRV-SEPARATORS.

Specification forming part of Letters Patent'No. 188,053, dated March 6,1877; application filed January 13, 1877.

To all whom it may concern:

- Be it known that I, JOSEPH G. HINOHMAN, of Medford, in the county ofBurlington and State of New Jersey, have invented a new and useful Improvemen t in Gran berry-Separators, of which the following is aspecification The figure is a vertical section of my improved machine.

The object of this invention is to furnish an improved machine forSeparating cranberries, which shall be simple ,in construction,convenient in use, and etfectixe in operation, separating the good andbad berries rapidly and thoroughly.

The invention will first be described in connection with the drawing,and then pointed out in the claims.

A is the case or frame of the machine, the rear side a of which ishinged at its upper end, so that it may be swung out to giveaccess tothe interior. The forward side a is inclined, and is hinged at its upperend, so that it may be swung outward to give access to the rollers andguide-boards. The forward side a is a frame, covered with cloth, so thatthe berries that strikeagainst it will not rebound. To the top of thecase A, at the opposite sides of a cross-slot formed in it, are securedtwo boards, B O, at such a distance apart that the berries may pass downbetween them. To the sides of the case A are pivoted four, more .orless, rollers, D, in such positions that the vertical plane passingthrough the axis of each lower roller may be about upon a tangent to theforward side of the next upper roller. In front of each roller D isplaced an inclined board, E, which is pivoted at its ends to the sidesof the case A, so that it may be adj usted at any desired inclination,To the sides of the case A, in front of the boards E, are attachedwires, from which are suspended short curtains F. To the sides of thecase A, between the boards E and the rollers D, are secured the ends oftwo boards, G H, at such. a distance apart that the berries can passdown between them. The lower edge of the board G is a little below thelower edge of the pivoted board E, and the lower edge of the board H isa little below the lower edge of the board G, and near the upper side ofthe next lower roller D.

The cranberries are .fed into the space between the two boards B 0 fromthe spout I, the bottom of which is a screen, and the outer end of whichis supported by aframe, J. The rapidity of the feed from the spout I isregulated by a feedboard, K, which is pivoted at its ends to the sidesof the spout I, and is provided with a handle, is, for convenienceincontrolling it. Around each of the rollers D passes a band, L, whichalso passes around a roller, M, pivoted to the rear part of the sides ofthe case A. To one of the journals of the roller M is attached a crank,N, for convenience in operating it. The roller M is also designed to beconnected by a band, 0, with a roller, 1?, pivoted to an upwardprojection of the sides of the case A, just below the lower part of thespout I, so that by turning the roller P the rollers D may be adjustedby the person attending the feedl In using the machine, as the berriesdrop through the space between the boards B O they strike the forwardpart of the upper side of the upper roller, and the perfect berriesbound over the upper edge of the inclined board E, and pass down fromone to another of the boards E until they are received in the box Q,placed beneath the forward lower part of the case A. The perfect berriesthat were prevented from bounding, and those that struck against theinner side of the board E, pass down between the boards Gr H to the nextroller, where the same operation is repeated, and so on, to the last,when the bad berries drop into the box R, placed at the inner side ofthe box Q. The boards El prevent any of the berries from bounding backthrough the space between the rollers D. The curtains F retard thedescent of the berries, and prevent them from bounding about as theypass from one of the boards E to another. The wholly soft berries crushupon the rollers D, and when so many have lodged upon them as to beginto interfere with the bounding of the perfect berries the rollers D areturned a little by turning the roller M or P to present a clean surfaceto the berries. Scrapers should be attached to the case A, at the rearside of the rollers D, to scrape off the soft berries, and thus keep thesurfaces of the rollers D clean. These scrapers are not shown in thedrawings.

Having thus described myinvention, I claim the inclined boards E and therollers D, subas new and desire to secure by Letters Patstantially asherein shown and described. ent- 4.
